It looks like I have trigeminal neuralgia. That seems the most logical explanation for a bout of right-side-of-the-face pain.
It had been disguising itself as dental pain for many months. Then one evening it attacked! Ibuprophen alone could not win against this rogue nerve. So my doc gave me some Tylenol laced with codeine. Now I know why I so enjoyed having a cold when I was a kid: it wasn't the missing of school that so delighted me; it was the codeine.
